[0002] Cleaning preparation for improved ease of application

[0003] The present invention relates to cosmetic cleansing preparations containing Tetramethyl acetyloctahydronaphthalenes (Iso E Super).

[0004] A person's outward appearance can be influenced and enhanced through the use of cosmetic products. Regular use of cleansing and care products ensures that people feel attractive, beautiful, and comfortable in their surroundings, and radiate this outwards.

[0005] The cleansing process serves the purpose of loosening and rinsing away dirt such as sweat residue or accumulated skin cells. For this purpose, shower gels and cleansing products typically contain anionic, non-ionic, or amphoteric surfactants. Surfactants enable, among other things, the dissolution of organic, particularly nonpolar, substances in water. Since, in addition to removing external dirt particles from the skin, they can also dissolve the skin's own particles, leading to dry skin or skin irritation. Therefore, it is important that a shower gel also cares for the skin. This can be achieved by using mild cleansing products and adding agents to replenish the skin's natural oils or moisturize it.

[0006] How effectively a cleansing product removes dirt from the skin depends on several factors. Besides the surfactants used, the application and rinsability of a shower gel also play a crucial role. It is essential that a shower gel can be absorbed into the skin as effectively as possible so that the surfactants can encapsulate dirt particles, making them water-soluble and easily rinsed away. During the application process, the cleansing product must spread easily on the skin, forming a film that can then be lathered and rinsed off with water. Therefore, the cleansing product should be formulated so that it can be applied to a surface without requiring excessive force from the user to spread it on the skin.At the same time, the cleaning preparation must also adhere to the skin so that a surfactant film can form, which can encapsulate dirt particles. The effectiveness of a cleaning preparation in applying surfactants to the skin, and thus in improving the rinsability of a cleaning preparation-dirt particle complex with water, can be defined by its absorbability. The absorbability of a cleaning preparation can be described by measuring the contact angle of a droplet of the cleaning preparation on a surface. The size of the contact angle describes how well the cleaning preparation can spread across the surface, which is directly related to the formation of a surfactant film and thus to rinsability. The smaller the contact angle of an applied cleaning preparation droplet on the surface, the better the absorbability of the cleaning preparation.A cleaning preparation exhibits high drawability at a contact angle (cleaning preparation droplet on surface) of < 18.5°.

[0007] The ease of application of a shower gel depends on the surfactant content in the cleansing formula. A higher surfactant content leads to better application. However, increasing the proportion of surfactants in shower gels should be avoided, as this could lead to reduced gentleness, skin irritation, and redness. Anionic surfactants in the form of sulfates, particularly sodium lauryl ether sulfate and / or ammonium lauryl ether sulfate, are frequently used in cleansing formulas.

[0008] Therefore, there is a particular need for cosmetic cleansing preparations that contain anionic surfactants and, moreover, exhibit good absorption properties when applied conventionally to a surface, especially wet skin, thus facilitating rinsing with water.

[0009] Furthermore, for environmental reasons, consumers increasingly prefer cleaning products that do not contain homo- or copolymers of acrylic acid, as their biodegradability is not yet fully understood. These polymers are used as thickening agents in cleaning products, adjusting the desired viscosity of the shower gel by thickening a liquid phase. Therefore, cosmetic cleaning products based on naturally occurring polymers or salts are increasingly being used.

[0010] Consequently, the object of the present invention was to provide cosmetic cleaning preparations containing anionic surfactants and exhibiting good adhesion to surfaces. Conventional cosmetic cleaning preparations consist, among other things, of

[0011] The cleaning preparations are known from EP1647591 A1 or EP2768474 A2. These preparations typically contain anionic and amphoteric surfactants. However, the disclosed preparations did not provide any indication of the present invention.

[0012] Surprisingly for those skilled in the art, it has now been found that the problem of applying a cleaning preparation to a surface could be solved by the present invention.

[0013] The present invention relates to a cosmetic cleansing preparation comprising, based on the total weight of the cleansing preparation, a) Tetramethyl acetyloctahydronaphthalenes; b) At least one anionic surfactant

[0014] A further object of the present invention is a cosmetic cleansing preparation comprising, based on the total weight of the cleansing preparation, a) Tetramethyl acetyloctahydronaphthalenes; b) At least one anionic surfactant; and c) At least one amphoteric and / or zwitterionic surfactant.

[0015] A further object of the present invention is a cosmetic cleansing preparation comprising, based on the total weight of the cleansing preparation, a) Tetramethyl acetyloctahydronaphthalenes; b) At least one anionic surfactant; c) At least one amphoteric and / or zwitterionic surfactant; and d) At least one nonionic surfactant.

[0016] Another object of the invention is the use of a combination of at least one anionic surfactant and tetramethyl acetyloctahydronaphthalenes to improve the draw-up properties of a cleaning preparation.

[0017] Surprisingly, the combination of the invention, or rather the cleaning preparation according to the invention, showed a significant increase in the applicability of the cleaning agent on a surface. The applicability could be determined by measuring the contact angle of a droplet of the cleaning preparation on a test area. Consequently, an improved applicability on a surface was surprisingly observed without increasing the surfactant content of the cleaning preparation. Any contact angle values ​​given in this disclosure refer to measurements taken at 25 °C. For this purpose, a test area on a polymethyl methacrylate plate (PMMA plate) was first cleaned with isopropanol. Then, a droplet (0.1 g) of the cleaning preparation was applied to the test area, and the angle between the surface of the cleaning preparation and the surface of the PMMA plate enclosing the cleaning preparation was measured.Since the surface of the cleaning solution droplet is curved, the contact angle was measured as the angle between the PMMA plate and the tangent to the surface of the cleaning solution droplet, starting at the three-phase contact line (PMMA plate, cleaning solution droplet, and air), encompassing the volume of the cleaning solution droplet. Five measurements were taken for each sample to determine the contact angle, and the mean value was then calculated.

[0018] Where weight percentages (wt%) are given below without reference to a specific composition or mixture, these percentages always refer to the total weight of the cosmetic cleansing preparation. Where ratios of components / substances / groups of substances are disclosed below, these ratios refer to the weight ratios of the components / substances / groups of substances mentioned.

[0019] The terms “according to the invention”, “advantageous according to the invention”, “advantageous in the sense of the present invention”, etc., always refer within the scope of the present disclosure to the preparation according to the invention, the use according to the invention and the method according to the invention.

[0061] Furthermore, it is advantageous in the sense of the present invention if the preparation is free of silicone oils.

[0062] The cosmetic cleansing preparations in question can be preserved using preservatives commonly employed in cosmetics. These include, for example, parabens such as methylparaben, propylparaben, ethylparaben, and butylparaben. However, the use of acid-based preservatives commonly used in the food industry is also advantageous. These include, for example, benzoic acid and / or salicylic acid and / or their salts. The inclusion of sodium benzoate is particularly preferred, with the proportion of sodium benzoate preferably being in the range of 0.2 to 0.65 wt.%, more preferably 0.3 to 0.55 wt.%, and most preferably 0.4 to 0.5 wt.% based on the total weight of the preparation.

In this way, cleansing preparations can be provided that meet ecological requirements.

[0067] In particular, it is advantageous if the homo- or copolymers of acrylic acid and / or methacrylic acid known under the INCI names, polyquaternium-7, are not included.

[0068] Furthermore, the cleaning preparations according to the invention may contain other substances selected from the group consisting of glycerin, propanediol and sorbitol.

[0070] The cleaning preparation according to the invention is advantageously characterized in that it exhibits a contact angle of 5° to 25° under normal conditions, more preferably 10° to 22°, and particularly preferably 15° to 19°. It was surprisingly found that the invention makes it possible to obtain preparations which significantly reduce the contact angle of an applied droplet of the cleaning preparation. The use of the invention significantly increases the effectiveness of the cleaning preparation with regard to its ease of application by the consumer to surfaces, especially human skin.

[0071] Comparative experiments and examples

[0072] The following examples are intended to illustrate the present invention without limiting it. Unless otherwise stated, all quantities, proportions, and percentages are based on the weight and total quantity or total weight of the preparations.

[0073] The following formulations were prepared for the comparative tests. Formulations Cf. 1 to Cf. 6 are not according to the invention, while Ex. 1 to Ex. 2 are according to the invention.

[0074] Measurement method: see description.

[0075] The cleaning preparations listed above were prepared and their properties investigated in a comparative test. The contact angles were determined as described in the instructions. Surprisingly, formulations containing tetramethyl acetyloctahydronaphthalenes showed a significantly lower contact angle. In contrast, formulations without tetramethyl acetyloctahydronaphthalenes showed a considerably higher contact angle and thus poorer application of the cleaning preparations.
